A simple random sample of 16 bicycle helmets had a mean

A simple random sample of 16 bicycle helmets had a mean price of x-$38.12. It is reasonable to assume that the population of helmet prices is approximately normal with population standard deviation a-$7.79. Is it appropriate to use the methods of this section to construct a confidence interval for the mean helmet price?
